CAREER: A Novel Approach for Large Eddy Simulation on Unstructured Grids Applied to Turbulent Jets in Cross-Flow

摘要CTS-0133837 K。本文采用非结构网格对横流中的湍流射流进行大涡模拟。 选择该问题是因为它适用于许多重要的技术问题，如喷油器，V/STOL飞机，涡轮机叶片的薄膜冷却等。此外，这样的流动不能正确地预测目前的计算格式的雷诺平均Navier-Stokes方程（RANS）。 非结构化网格的选择，以允许网格点被定位在射流边界附近和附近的壁。 计算方法将基于PI开发的动能守恒方案。 将结果与现有的实验数据进行比较。 大涡模拟方案一旦得到充分发展，将应用于一系列其他流动。教育计划包括开发新的研究生课程，将研究部分纳入研究生和本科生课程，并将本科生纳入研究项目。

Abstract CTS-0133837K. Mahesh, University of MinnesotaIt is proposed to perform large eddy simulation (LES) of turbulent jets in cross-flow using unstructured grids. The problem is chosen because its applicability to a number of important technical problems such as fuel injectors, V/STOL aircraft, film cooling of turbine blades and etc. Furthermore such a flow cannot be correctly predicted by the current computational scheme of Reynolds-averaged Navier-Stokes equations (RANS). Unstructured grids are chosen to allow mesh points to be localized near the jet boundary and near the wall. The method of computation will be based on a kinetic energy conserving scheme, which was developed by the PI. The results will be compared to existing experimental data. The LES scheme, once fully developed, will be applied to a range of other flows. The education plan involves development of new graduate courses, incorporate research component into both graduate and undergraduate courses, and including undergraduate students in research projects.
